Demon Form Bug After Patch (POE 2)

I don't know if other players felt it, but it seems that the demon form formula is bugged, the skill shows that it has leveled up but does not increase mana costs, the damage is now much lower than the damage with an average weapon, around 40 Lower % even with 10 stacks, my damage without demon form is 2900, when activating demon form the damage drops to 1800 and only increases by 50 with each stack totaling 2300 damage with the 10 charges, meaning I spent 4 ascension points and sacrificed 5% of my life per second to reduce my damage.

It seems they also broke something about second wind. The skill remains on cd even after i drop out of demon form when using second wind.
